ABSTRACT:
This disclosure relates to a water craft or boat including an engine room for an engine. The room is closed except for an opening through which intake air moves into the room, whereby the engine is supplied with intake combustion air. An exhaust line also extends between the engine and the outside of the room. Cooling means is provided in the room to collect coolant discharged from the engine and to inject it into the exhaust line in the room, whereby the coolant is discharged out of the room together with exhaust gas from the engine. Fuse means is provided in the exhaust line in the room downstream from the location where the coolant is injected. The fuse means is heat fusible to thereby form an opening when the gas in the exhaust line exceeds a predetermined temperature, whereby exhaust gas enters the room through the opening. The exhaust gas is drawn into the engine intake, causing the engine to fail to operate or to falter.
